Hypertrichosis
Hypertrichosis, congenital generalised Hypertrichosis or werewolf syndrome is a medical term referring to a condition of excessive body hair. Werewolf syndrome comes from the characteristics of a mythological werewolf of which the person is completely covered in hair or fur. It can be generalised, symmetrically affecting most of the torso and limbs, or localised, affecting an area of skin. It may be mild or severe. In most cases, the term is used to refer to an above-average amount of normal body hair that is unwanted and is an aspect of human variability.
A slight genetic variation or variation in hormone signalling can turn the fine downy hair which covers our bodies into full thickness hair.
The hair follicles on much of the body respond to androgens (primarily testosterone and its derivatives). Generally, the rate of hair growth increases and the heaviness of the hairs increases in direct proportion to the androgen levels. However, different areas respond with different sensitivities.
Severe hypertrichosis is quite rare, almost certainly due to unknown genetic defects, and can result in excessive or animal-like hair on both face and body. Some of these people have been displayed in carnival side shows with names such as "dog-boy" or the "bearded lady." In some cases an area of skin can react to repeated trauma or to some other asymmetric stimulus (such as wearing of a cast) with increased hair growth.
The treatments range from camouflage (e.g., bleaching with hydrogen peroxide), to temporary removal by waxing, or permanent removal by electrolysis or laser destruction of hair follicles.
